The ARO 6661AJ-3EB-C is a 1" air-operated double-diaphragm (AODD) pump from ARO's Pro Series 1" non-metallic line — self-priming, run-dry capable, and rated to about 47 GPM on compressed air up to 120 psi.

This build runs an all-polypropylene wetted path — fluid caps, manifold and seats — with Santoprene diaphragms and Santoprene check balls. Santoprene is a tough, value-oriented elastomer with good general chemical compatibility, well suited to water-based and mildly aggressive fluids. Bolted construction keeps the fluid path leak-tight, and ARO's patented unbalanced air valve is designed to resist stalling and ice-up.

It is built for higher-volume transfer, filling, recirculation and supply in chemical, industrial and water/wastewater service. Not sure this build suits your fluid? Send us your application details and we'll point you to the right part number.
